This is a 1.5 kilowatt spindle which roughly translates to 2.01 HP. The spindle is water cooled which requires a pump and tubing. We are using a 300 gal/hr pump that can be purchased from the home improvement store submerged in a bucket of water, but a chiller can also be used.
Do not attempt to wire your VFD or spindle on your own. Consult with a professional electrician before following the diagram.
